Google's proposed Web Environment Integrity (WEI) specification has raised concerns among browser developers and users, as it could potentially allow websites to restrict access based on the user's browser and platform. The specification would provide an API for websites to verify the authenticity of user interactions, but critics argue that it could be used to exclude certain browsers or platforms. The proposal has been likened to DRM for the web, and some argue that it could lead to a loss of user freedom and choice. Google has since announced that it will not proceed with the WEI specification, but some commentators remain skeptical about the company's intentions.
